岁月在墙上剥落看见小时候琴声悠悠我得等会你没听过
[suì yuè zài qiáng shàng bō luò kàn jiàn xiăo shí hòu qín shēng yōu yōu wŏ dé dĕng huì nĭ méi tīng guò]
This is a poetic phrase translating to 'time peels off the wall showing childhood with melodies lingering; I have to wait because you've never heard'. It reflects nostalgia, longing for past moments and music that someone dear to them has never experienced.
